Hey girls ? Who had such a big difference from the second pregnancy compared to the first? I had my first boy, toxemia wasn't there at all, I woke up from the smell of meat and gnawed in the 2-3 hours of night ?was full of strength and energy, overall enjoyment rather than pregnancy) Now the second one, it's a nightmare, constant nausea all day long, I can't look at food, although already ultrasound 13 weeks 4 days, no strength, broken whole walking around, face with pimples like a teenager, and here on the first screening they said Boy) Could it be that such a difference happens with single pregnancies?
